An old elevator is inferior to the latest one in terms of safety, comfort, reliability

and energy savings, as well as in design. In order to make in-building travel safer

and more comfortable and to enhance the value of a building or property, eleva-

tor modernization is indispensable.

The average elevator replacement cycle is 20 to 25 years.

Elevators which have passed 20 years of service since installation are recom-

mended to be modernized to meet the standards or specifications of latest

models.

Even with periodic maintenance, it is generally difficult

to maintain optimal elevator performance beyond the original service life.

As user requirements and social needs change over time,

the original elevator performance itself no longer meets the needs of the times.

Under such circumstances, owners and managers are now requested to maintain and even improve elevator safety and security from the standpoint of elevator users.

SecurityWith old elevators, there is a growing risk for failure or accidents, which may trigger more unexpected trouble. By modernizing, electrical systems that have higher risks for failure due to age, while usable parts remain unchanged, will be replaced and upgraded. For durable goods such as elevators, we do not recommend makeshift repairs.

The Control Panel (COP) is a device located in an elevator

machine room on the rooftop of a building and controls

elevator operation and speed. So-called elevator’s brain,

the COP is an important device. But with the passage of

service years, deterioration appears earliest in the COP.

Elevator drive system will be updated. Existing traction machine and existing thyristor panel operating in the elevator drive sytem will be

reused. This plan promotes a low-cost elevator renewal. Existing DC gearless machines and thyristor panels can continue to be used in Plan

A. (For motor-generator-equipped DC gearless machine types, Plan A cannot be applied.)

Fujitec provides three packages for elevator modernization depending on traction machine type and drive control system model. For

all three packages, the control system of the control panel (incorporating logic control circuits) will be upgraded to the latest type. For

elevators operating under a group supervisory control, their group supervisory system will also be upgraded to the latest type Flex-NX

Series. This system renewal will increase both elevator operating efficiency and passenger transportation capability.

Plan A Thyristor (Re-use) Drive Control

� Comparison of Product Packages

Elevator drive system will be upgraded; existing drive system will be changed to an exclusively developed type, the DC Chopper; and existing

machine will be reused. The DC Chopper Drive Control can be applied to the system of gearless machines that employs motor generators

and thyristors. In Plan B, existing DC gearless machines will continue to be used with the addition of a DC Chopper Drive Panel.

Plan B DC Chopper Drive Control

Existing traction machine models will be changed from DC gearless to the latest PM gearless. This machine-model change can be applied

to all existing DC gearless elevators. Along with this model change, elevator drive control system will be upgraded to be used with PM

gearless machines and main drive panels (including inverters and converters) will be modernized.

Installing a Destination Floor Guidance System (DFGS) as well as updating the elevator group

supervisory control system can also lead to a further increase in passenger handling capacity.

One of the main features is the capability to manage and control elevators remotely. This is

accomplished by monitoring the status of elevators and giving necessary commands to them

from the central control station in a building.

This technology can provide cleaner air more efficiently than conventional ventilation system.

Safety and Security

Being Trouble-free is the Best Solution

Before After

Prevent Tripping due to Leveling Error

Just replacing deteriorated parts is not enough

to eliminate the risk for failure or accidents. The

replacement or repair of deteriorated parts do

nothing more than to partially or temporarily stop

deterioration from age and usage.

On the other hand, through modernization, older

or antiquated microcomputer-controlled systems

are replaced with the latest high-performance

microcomputer-controlled systems.

Therefore, basic elevator performance will be

brought to the latest standards, and safety. In

addition, comfort and cost effectiveness will be

dramatically enhanced.

Updating Door Control UnitInverter control for door control units, door motors, etc. will be installed. This application stabilizes door closing and opening opera-

tions, and also enhances passenger safety by minimizing door closing force.

Daily Essential InspectionBrake inspection operation will be automatically performed once every day, late at night or early in the morning; when there are few

passengers in order to diagnose brake performance.

The elevator detects abnormalities, ensuring appropriate preventative maintenance.* Please note that the above operation will not apply to Plan A. (See page 3.)

Elevator Operating Efficiency

In conventional elevator control systems, the Creep Operation is

necessary in order to reduce car traveling speed for landing at a

destination floor. The car-creeping time, which occurs before the

car’s arrival at a destination floor, is programmed in the car's

total traveling time. With newer elevator control systems, the

Creep Operation is no longer needed. By using Fujitec-

modernized elevators, total car traveling time will be shortened

and passenger transportation capability will be increased by 8 %*

as compared to conventional models.

* The figure is based on data obtained from elevators with speeds traveling up to 210 mpm in a 20-story building.

Multibeam Sensor Option

Function Improvements and Energy Savings

Elevator Leveling Accuracy

Power Consumption

Existing analog-type elevator control systems are susceptible to changes in ambient temperature, which can adversely affect leveling

accuracy. Current digital control systems are highly resistant to changes in the surrounding environment. Therefore modernizing an

elevator's control system will increase car leveling accuracy much more than was possible before.

Modernized elevators consume less electricity than conventional

elevators. This was found in comparative data representing

power consumption in both types by testing under identical

conditions; such as the same number of elevator starts, the same

carload of passengers, etc.

� Comparison of Operating Time : Conventional DC Gearless vs. Modernized Model

* This is just an example; actual model may differ.

The latest inverter control ensures excellent landing precision.

Infrared beams along the full opening height of the doors will create an invisible beam curtain.

Interrupting any of the beams will cause the closing doors to stop and reopen. Through the

use of multi-infrared beams, the sensor features high detectability of a moving person or

object while the door is closing.

* Only two beams are available for some elevator models.
